摘要

摘要: 目的以类风湿关节炎（rheumatoid arthritis，RA）患者为研究对象，观察芳香烃受体（aryl hydrocarbon receptor，AHR）在患者外周血CD4⁺CD25⁺T 细胞中的表达水平，探讨AHR在RA发病机制中的意义。方法采用流式细胞术检测RA患者（35例）及健康对照组（14例）中AHR 阳性细胞在外周血CD4⁺CD25⁺T 及CCR6⁺CD4⁺T细胞中所占比例，并将所得结果与患者临床指标的相关性做分析。结果 RA 组外周血CD4⁺CD25⁺T细胞中AHR 阳性细胞所占比例为（17.90（6.10，80.10））%，低于健康对照组（52.43（19.18，96.43））%，差异有统计学意义（Z=-4.362，P<0.001）；正常对照组外周血CD4⁺CD25⁺T细胞中AHR阳性细胞比例为（52.49±19.18）%，高于CCR6⁺CD4⁺T细胞中（23.18±5.62）%，且都高于外周血单个核细胞（peripheral blood mononuclear cells，PBMCs）中（18.06±7.80）%，三组间差异有统计学意义（χ²=24.03，P<0.001）；RA组CD4⁺CD25⁺T细胞中的AHR比例为（17.90（6.10，80.10））%，低于PBMCs中的（34.43（8.72，56.37））%，且都低于CCR6⁺CD4⁺T细胞中的（46.15（20.18，87.31））%，三组间差异有统计学意义（χ²=38.29，P<0.001）。结论 RA外周血CD4⁺CD25⁺T细胞中，AHR 阳性细胞比例降低，而在CCR6⁺CD4⁺T细胞中升高，AHR可能通过调节辅助性T细胞17与调节性T细胞细胞的分化，影响Th17与Treg之间的平衡，从而参与RA的发病机制。

Abstract: Objective To explore the significance of aryl hydrocarbon receptor (AHR) in the pathogenesis of rheumatoid arthritis(RA) by detecting the percentage of AHR positive in CD4⁺ CD25⁺T cells. Methods Peripheral blood of 35 patients with RA and 14 healthy controls were collected. Flow cytometry (FCM) technology was applied to detect the proportion of CD4⁺ CD25⁺T cells and AHR positive cells in peripheral blood of each individual and the percentage of AHR positive cells in CCR6⁺CD4⁺T cells were also tested. Clinical data was recorded in detail and disease activity score in 28 joints (DAS28 ) was calculated. Then, the association between the percentage of AHR positive cells in CD4⁺ CD25⁺T cells and clinical data was analyzed. Results In peripheral blood of RA patients, the percentage of AHR positive cells in CD4⁺CD25⁺T cells was significantly lower than that in healthy controls ((17.90(6.10,80.10))% vs.(52.43(19.18,96.43))%,Z=-4.362,P<0.001); In peripheral blood of healthy controls, the percentage of AHR positive cells in CD4⁺CD25⁺T cells was significantly higher than that in CCR6⁺CD4⁺Tcells, and was also significantly higher than that in peripheral blood mononuclear cells(PBMCs) ((52.49±19.18)% vs. (23.18±5.62)% vs. (18.06±7.80)%, χ²=24.03, P<0.001); In peripheral blood of RA patients, the percentage of AHR positive cells in CD4⁺CD25⁺T cells was significantly lower than that in CCR6⁺CD4⁺T cells, and was also significantly lower than that in PBMCs((17.90(6.10,80.10))% vs. ((46.15(20.18,87.31))%vs. (34.43(8.72,56.37))%, χ²=38.29, P<0.001); Nevertheless, no statistically significant correlation was found between clinical data and the percentage of AHR positive cells in CD4⁺ CD25⁺T cells. Conclusions AHR may participate in the pathogenesis of RA by controlling the differentiation of Th17 and Treg cells .
